Hydrophobic organo-compatible but low-capacitance dielectrics (10.5 nFcm-2), polystyrene-grafted SiO2 could induce surface-mediated large crystal grains of face-to-face stacked triethylsilylethynyl anthradithiophene (TES-ADT), producing more efficient charge-carrier transport, in comparison to μm-sized pentacene crystals containing a face-to-edge packing. Low-voltage operating TES-ADT OFETs showed good device performance (μFET ≈ 1.3 cm2V -1 s-1, Vth ≈ 0.5 V, SS ≈ 0.2 V), as well as excellent device reliability.
